How Do Water Purification Tablets Work?

There are many different water purification tablets available on the market.

Best Water Purification TabletsThis sadly means that each one requires a specific dosage to work properly. There isn’t a universal dosage amount.

However, all the best water purification tablets work in a similar way.

The usage is typically 1 or more tablets in a large container of water. Then close the container for at least 30 minutes for it to work.

But always remember to read the instructions to know how to get the best results from individual brands.

Water Purification Tablets Vs Filter

Water purification tablets are a cheaper, smaller method of water filtration that is not as effective as a water filter device but good for emergencies.

Water Purification Tablets

Water-Purification-Tablet-Infographic

The first thing to know is that water purification tablets do not remove chemical pollutants or physical particles. If you ever face chemically polluted water, especially if it contains sediments then know that it will require much more filtration than a purification tablet is capable of providing.

Water-Purification-Tablet-InfographicIf you find particles in the water you want to drink, make sure you remove them as a purification tablet probably won’t remove it and you don’t want it to dissolve as that could add more hazardous material into the water.

If you find any sign of chemicals in the water then do not try to purify instead find an alternate source of water.

Chlorine dioxide is the most effective at killing most microorganisms, however, also note that it requires a longer treatment time than iodine or chlorine.

Finally, purification tablets usually leave an unpleasant aftertaste unless otherwise stated on the packaging.

Filtered Water

On the other hand, if you use something like a filter jug or a home installed filtration unit then it will remove far more impurities and this includes all chemicals, micro-organisms and dissolved substances.

Tablets Vs Filter: The Key Difference

Green Plus ArrowIn essence, there really is no competition. Filter water beats water filtration tablets on almost every count; filtered water is cleaner and tastes better than water purified with tablets.

Can You Use Iodine Tablets To Purify Water?

Yes but it won’t taste very nice.

As mentioned in the previous section, some purification tablets are known to leave behind an unpleasant taste and that lead to the invention of the iodine neutraliser tablet, which is designed to neutralize flavour.

Although sometimes there are other ways of removing unpleasant tastes from the water.

For example, chlorine flavour can easily be removed if you let the treated water sit uncovered so that the chlorine can eventually evaporate by itself.

If taste is very important to you then you should consider buying purification tablets that are flavoured with fruit or something nice.

Best Water Purification Tablet Brands

The “best” brand and type of water purification tablet will depend on a number of different things. For example, how much water will you need to purify? How dirty will the water be? What kind of contaminants do you want to remove?

The following list are some of the brands that produce purification tablets and a review of individual products will be discussed later in this article.

Best Water Purification Tablets: Final thoughts…

The best water purification tablets are small tablets that remove harmful micro- organisms in water. They work by killing pathogens present in water and make it safe for human consumption.

However, note that these tablets do not remove chemical pollutants or physical particles and the best way of filtering water is still to use a water filter jug or methods like charcoal filtration and reverse osmosis.Mr Water Geek Happy

Using a specialised water filter beats purification tablets on almost every count as they purify water that is cleaner and tastes better. Tablets should only be used when there are no other options and as a last resort.

You are facing a desperate need for clean water and don’t have a purification tablet at hand but still need to make sure water is clean enough to drink?

Boil it.

Boiling water is very effective at removing most of the harmful microorganisms.

It is important to note that taking one of the best water purification tables mentioned in this post. Or iodine tablets for that matter, can pose health risks for people with iodine allergies or thyroid conditions. Finally, it is not advisable for women who are pregnant to consume such tablets.
